My code hasn't changed in any significant way, but for some reason my save file dialog now flickers open, then closes and the show dialog result returned is false. It was working flawlessly for some time, but now it is doing this. Has anyone else seen something like this?

C#

internal string BrowseForSaveAsDoc()
        {
            SaveFileDialog dlg = new SaveFileDialog();
            dlg.CheckPathExists = true;
            dlg.CheckFileExists = false;
            dlg.DefaultExt = ".docx";
            dlg.AddExtension = true;
            dlg.Filter = "Word Documents (*.docx)|*.docx";
            var res = dlg.ShowDialog();
            if (res == true)
                return dlg.FileName;
            return "";
        }

I instantly see res as false when I set a breakpoint on the if statement. It was working flawlessly just the other day. Is there something funky that happened to my computer or something?

Ok I figured out what is happening. The button that executes the show modal actions is inside a wpf popup control. I modified the popup to StaysOpen="false". So the popup hides the moment it loses focus (when the modal shows up) and thus the context that called the modal is killed so it just cancels itself out.

A side note: Don't write return "", use string.Empty (or null if you wish). Avoid immediate constants (such as "") in all cases.
